SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent N 0. 732,392, dated June 30', 1903.

Application filed January 2'7. 1902. Serial No. 91,502. (No model.)

To ctZZ whom, it may concern:

Be it known that I, CHARLES D. BROU- YETTE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring Bed-Bottoms, of which the following is a specification.

My invention relates to improvements in the manner of securing spiral springs in the lower surface or base of a conical spiral spring bed-bottom; and its objects are, first, to lessen the cost of construction; second, to greatly strengthen the base against being thrown out of square, and, third, to so unite the parts as to positively prevent separation or dislocation unless it be desired to repair the spring and yet be so that the spring may be readily and easily removed without injury to or distortion of parts. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a bottom plan of a portion of a spring andbase, showing the manner of securing the springs to the tie-rods of the base. Fig. 2 is an elevation of the same; and Fig. 3 is a plan of the tie-rods, showing the manner of introducing and applying the spring and passing it to position to secure it to the tie-rods.

Similar letters refer to similar parts throughout the several views.

In the construction of this base the longitudinal tie-rods A have a depression a a a formed for the reception of each spring and the lateral tie-rods B have an offset 19 b b, which coacts with the longitudinal tie-rod A and the end of the spring 0 to form the support for the springs, and they are woven together as follows, which is the only way the spring can be connected with the base.

In Fig. 3 the lateral and longitudinal tierods are shown as in position with the bedbottom bottom side up and the tie-rods held firmly in place to receive the lower ends of the springs, and to enter the spring it must be held with the base of the cone upward as shown, and the endo Cmustbe passed through under the oifset in the lateral tie-rod between it and the longitudinal tie-rod at the depression at in position so that end C may be drawn back over the arm of the offset in the lateral tie-rod, as shown, when the base of the spring must be carried over in the direction of the arrow toward D and passed between the tie rods and to place below them, as indicated by the dotted lines in Fig. 3 and as shown in Figs. 1 and 2, so that the portion 0 of the spring will rest in the depression a, and the spring having been carried over the end C rests upon the top of the lateral tie-rod and against the side of the longitudinal tie-rod, formin g a brace or braces that will avert the danger of throwing the bed-bottom out of square. The portionc passes thence over the longitudinal tie-rod, under the opposite arm of the 6 offset in the lateral tie-rod, and thence over the rod and under the longitudinal tie-rod at C, where it presses upon the rods with sufficient force to cause a firm bearing of the portion-c upon the portion a of the depression in the longitudinal tie-rod, and the portion 1) of the offsetin the lateral tierod rests against the longitudinal tie-rod at a. It is evident that this connection cannot be made in bedbottoms where it is desired to use the hour glass spiral spring, but with the single cone made to alternate right and left the construction is so firm, by reason of the brace secured by the ends 0, as hereinbefore suggested, that it is practically impossible to throw the bed out of form diagonally, thus securing a practically square bed-bottom under all conditions. I

-If it is desired to remove a spiral spring from this construction, the spring must be swung back between the tie-rods in a direction opposite that indicated by the arrow in Fig. 3 and up to the position of the solid lines in said figure and spring the end C i from over the lateral tie-rod at b, when the end 0 C may be drawn from its bearings between the tie-rods and the spring readily removed. By this means a bed-bottom may be readily repaired without bending or distorting the tie-rods when removing the spring, 9 5 and, further, the hooked end C may be formed upon the end of the spring while in the process of being coiled'and the. spring complete inserted much more quickly and conveniently than with any other construction now practiced.

It is not absolutely necessary that the end C of the spring be made to press solidly against the side of the longitudinal tie-rod; but I consider it far preferable in consequence of the greater strength thereby gained and the perfect form of bed attained and retained.

The vital feature of this invention, which is my discovery, is the reversing of the position of the spiral spring with reference to the base wires in order to assemble parts or remove them from each other.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination in a spring bed-bottom of longitudinal tie rods having depressions, lateral tie-rods having V-shaped offsets extending beyond the depressions and bearing upon the surface of the longitudinal tie-rod, a conical spring having one end near the side of the longitudinal tie-rod thence passing to one point of angle of the offset, forming a hook and passing around the lateral tie-rod at the point of angle, thence across the longitudinal tie-rod in the depression, thence to and around the lateral tie-rod at the other point of angle of the offset, thence a coil of the spring passing across the longitudinal tierod in position to exert the torsional force of the spring upon the offset of the lateral tierod interweaving it with the longitudinal tierod, substantially as and for the purpose set forth.

2. The combination in a spring bed-bottom of longitudinal tie-rods having depressions, lateral tie-rods having'V- shaped offsets the point of said offsets bearing upon the surface of the longitudinal tie-rods near the points of angle of said depressions, spiral springs having the ends near the sides of the longitudinal tie-rods, thence under and around the lateral tie-rods at the point of angle of the offset forming a return hook and passing under the longitudinal tie-rod at the point of depression, thence over and around the lateral tie-rod at the other point of angle of the offset, thence over the longitudinal tie-rod, substantially as and for the purpose set forth.

The combination in a spring bed-bottom of a coil-spring, a transverse wire having a long V-bend, and a longitudinal wire, interwoven by the wires having the following positions relatively: the wire of the coil-spring passing, commencing at one end thereof, under the transverse wire and over the adjacent leg of said long V-bend, under the longitudinal wire, over the other leg of the long V-bend and under the transverse wire adj acent thereto, and over the longitudinal wire, thence continuing in a coil which is substantially at right angles to the plane of the web-wires which intersect at the apex of the long V-bend, the transverse wire passing over the longitudinal wire, substantially as and for the purpose set forth.

4. In a spiral-spring bed-bottom, a longitudinal tie rod having depressions, lateral tie-rods havin gV-shaped offsets, spiral springs interwoven therewith by resting on the longitudinal tie-rod, thence passing under the lateral tie-rod and around over the arm of the oifset at the point of angle, thence under the longitudinal tie-rod at the depression, to and over the other arm of the offset and around under the tie-rod at the opposite point of angle, thence the end extending to, and at right angles with the side of the'longitudinal tie-rod, substantially as and for the purpose set forth.

Signed at Chicago, Illinois, J anuary15, 1902.
